QUOTE : The analysis of our illustrations has taught us another incidental lesson. This is that, when we study the effects of various proposals, not merely on special groups in the short run, but on all groups in the long run, the conclusions we arrive at usually correspond with those of unsophisticated common sense. It would not occur to anyone unacquainted with the prevailing economic half-literacy that it is good to have windows broken and cities destroyed; that it is anything but waste to create needless public projects; that it is dangerous to let idle hordes of men return to work; that machines which increase the production of wealth and economize human effort are to be dreaded; that obstructions to free production and free consumption increase wealth; that a nation grows richer by forcing other nations to take its goods for less than they cost to produce; that saving is stupid or wicked and that squandering brings prosperity.
